[PATCH v2 0/3] PM: dpm_watchdog: Improve DPM watchdog configurability

[Tzung-Bi Shih <tzungbi@kernel.org>]

This series improves the configurability of the DPM watchdog.

Currently, the DPM watchdog timeouts are fixed at compile time, and the
watchdog is always enabled if compiled in.  Also, the module parameters
defined in drivers/base/power/main.c use the generic and non-descriptive
"main" prefix.

This series addresses these limitations.

Patch 1 renames the module parameter prefix for drivers/base/power/main.c
from "main" to "power".

Patch 2 introduces the CONFIG_DPM_WATCHDOG_DEFAULT_ENABLED to allow the DPM
watchdog to be disabled by default at compile time.  It also exposes the
"power.dpm_watchdog_enabled" module parameter to allow enabling/disabling
the watchdog at boot time and runtime.

Patch 3 introduces sysctl knobs under /proc/sys/kernel/ to allow
configuring the DPM watchdog timeouts at runtime.
